To all whom it may concern:

Be it known that I, EDWARD T. BUReEss, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in SolderingFurnaces, ofwhich the following is a specification.

My invention relates to the improvement of soldering furnaces, and theobjects of my invention are to provide a soldering furnace of superiorconstruction and arrangement of parts; to provide improved means formaintaining a constant and uniform generation of gas in the gasoleneconducting pipe; to provide improved means for support-ing a solderingiron in position for receiving the heat from the burners and tootherwise produce an improved soldering furnace of simple, compactarrangement so constructed as to insure a soldering iron supportedtherein, being subjected to a uniform high degree of heat, and toproduce other improvements the details of which will be more fullypointed out hereinafter. These objects I accomplish in the mannerillustrated in the a'ccompanying drawing, in which:

Figure 1 is a central longitudinal section of my improved solderingfurnace, Fig. 2 is an enlarged transverse section on line of Fig. 1,and, F ig. 3 is a front elevation of my improved furnace.

Similar numerals refer to similar parts throughout the several views.

1 represents a horizontal supporting base, which is preferably of theinverted pan form shown. Rising from this an near one end thereof, arethe vertical si e and end walls 2 and 3 of my improved soldering furnacebody, said end walls being rovided with central vertical recesses 4 an 5formed in their upper sides, said oppositely located recesses forming asupport for a horizontally disposed central pipe 6, which in rear of thestove body, connects with a vertical gasolene tank 7. The pipe 6 isintersected near the tank 7 by a suitable cut-off and regulating valve8. The forward end of the pipe 6 which projects, as shown, beyond thefront i plate or wall of the stove body, is connected with the upperhorizontal member of an angular pipe sect-ion or valve casing 9, thedownwardly extending member of which is connected with an angularbracket 10 which projects from the front wall 3 of the stove body. Thedownwardly extending member 9 is formed with a forwardly projecting boss9L within the central vthreaded opening of which is fitted a horizontalneedle point valve 11, said valve intersecting the lower portion of thepipe member 9 and having its pointed termination entering and adapted toclose a needle valve opening 12 in the rear wall of said member 9.

Beneath the pipe member 9, I provide a desirable form of cup 13 which isconnected, as shown in Fig. 1, with the lower end of the bracket 10.Secured to the front face of the stove body on either side of the centerof the width thereof above the'cup 13 and on the outer side of the pipemember 9, is a perforated shield plate 14. Beneath the pipe G andextending rearwardly through the front wall of the stove body, is a gassupply pipe 15, the latter at its rear end, connecting with the lowerportion of a fiattened box or ob long casing 16 which is secured to orformed with the inner face of the rear wall 3 of the stove body.

As shown more clearly in Fig. 2 of the drawing, the upper portion of thecasing 16, is bifurcated or centrally recessed to permit of the passagetherethrough of the pipe G and on each side of said central recess orbifurcation, I provide an elongated hollow burner body 17, which burnerbodies extend in the direction of the length of the stove and areprovided with inclined inner sides 17 a, through which are formedupwardly inclined parallel burner kerfs or slits 18. Above each of theseburners and extending lengthwise of the stove body, is provided asoldering iron supporting plate 19, the latter extending inwardly fromthe side walls of the stove body and thence inclining downward to meetthe upper sides and forward portions of said burners. Each of theseplates 19 has formed thereon, upwardly projecting parallel inclined ribs19a. The distance between the inner ends of the opposing ribs is such asto admit of a soldering iron being supported by said rib ends withoutpassing between the same.

In the construction of the pipe 15, it will 'be observed that I form inthe upper side thereof, a longitudinal slotted opening or burner kerf 20and on the inner and outer sides of the slotted portion of said pipe, Iprovide perforated plates 21 and 22. Above the pipe 9 and the perforatedshield 14, I pivot at one side of the center of the stove front, asindicated at 23, one end of a semidish shaped shield 24, the remainingend of which is notched to provide for detachable engagement with a stud25, which projects from the front of the stove body. Upon the stove bodyis detachably seated, a suitable form of cover or hood 2G, which isformed with a forward side opening 26a and an up per side opening 261.In order to provide a suitably located and braced handle, by which myimproved' stove may be supported and balanced, I connect with theforward side of the upper portion of the gasolene tank 7, a forwardlyextending arm 27 on which is mounted a Suitable handle member 2S. Fromthe forward end of the arm 27 lead outwardly and downwardly on oppositesides of the stove body, brace arms 29, these arms having their lowerends secured at opposite points to the sides and forward portion of thebase 1.

In utilizing my device, it will be understood that. the cup 13 isfirstsupplied with a comparatively small quantity of gasolene, whichwhen lighted, results in the heating of the pipe member f) so that thegasolene which passes through the pipe 6, will through contact with saidheated pipe be converted into gas. The gas thus produced is by theturning of the needle valve 11, permitted to pass through the needlepoint opening 12 into the open end of the pipe 15 and through said pipeand casing 16 to the burners `17, which communicate with said casing, asshown in Fig. 2 of the drawing.

In order to maintain gas generation within the pipe 6, I have providedthe burner kerf or opening 2() in the pipe 15 and by lighting the gaswhich escapes through said kerf, heat from the flame produced, will bedirectly imparted to the underside of said pipe G. It is desirable,however, that a comparatively small flame be maintained at the burneropening 20 and that the greater volume of be carried beyond said opening2O to the burner openings and inl'order to insure a comparatively smallflame from the opening in the pipe 15 and at the same time prevent atendency of the gas in said pipe from being drawn through the opening 2Oin undesirable volume, I have provided the perforated baffle plates 21and 22 which will tend to ret-ard the escape of the gas through theopening 20. It is obvious that a soldering iron when supported by andbetween the inner end portions of the ribs 19a, will be subjected to theheat of the flames at the burner openings 18 and owing to theinclination of the supporting ribs 19, it is evident that the solderingiron will be retained in a central position above the flames from theburners.

From the construction and operation described, it will be understoodthat the pipe 15 will act as both a gas supply and burner pipe and thatthe pipe 6 will perform the double oiiice of a supply and generatingpipe.

Owing to the pivotal connection of the shield or hood 24 with the stovebody, it will be understood that in case it is desired to disconnect andremove the pipe from the stove, said hood or shield may be swung to oneside to permit a free withdra 'al of said pipe.

lVhat I claim, is:

1. In a soldering furnace, the combination with a stove body, opposingburners arranged in said body, and a gasolene supply pipe extendingbelow said burners, of a gas conducting pipe extending beneath saidgasolene supply pipe and having a burner opening therein, said gasconducting pipe being connected with said opposing burners, and meansfor discharging gas generated in said gasolene supply pipe into theforward end of said gas conducting pipe.

2. In a soldering furnace, the combination with a stove body, a hollowburner therein, and a gasolene supply pipe beneath said burner, of a gasconducting pipe below the gasolene pipe and having a burner opening, aperforated plate partially closing said burner opening, a connectionbetween the rear end of said gas pipe and said hollow burner, and meansfor discharging gas generated in said gasolene pipe and its connectionsinto said gas pipe.

3. In a soldering furnace, the combination with a stove body, hollowburners supported therein, a gasolene supply pipe extending below saidburners, an angular pipe extension at the forward end of said gasolenepipe, and an adjustable valve intersecting said pipe extension, of a gasconducting pipe beneath the gasolene pipe having a burner openingtherein, a gas conducting connection between said gas pipe and saidhollow burners, and inclined soldering iron supports above said burners.

4. In a soldering furnace, the combination with a stove body havingvertical end recesses, a gasolene conducting pipe extending through saidrecesses, and burners above said gasolene pipe, of a gas conducting pipebelow said gasolene pipe and connected with said burners, said gasconducting pipe haying a burner opening, and means `for 'd1scharging gasfrom the gasolene pipe into said gas conducting pipe, and a shieldcrossing the forward recess in said stove body and pivoted on one sidethereof.

In testimony whereof I ailix my signature in presence of two witnesses.
